||It has been suggested that Bibliographic control be merged into this article. (Discuss) Proposed since July 2014.|
Cataloging (or cataloguing) is the process of listing something for inclusion in a catalog. In library and information science, the process encompasses the production of bibliographic descriptions of books as well as other types of discovery tools for documents. Today cataloging study and practice has broadened and merged with that of metadata ("data about data contents"), increasingly associated with Resource Description and Access.
Catalogers are responsible for the processes of description, subject analysis, classification, and authority control of library materials. Catalogers serve as the "foundation of all library service, as they are the ones who organize information in such a way as to make it easily accessible".

Types of cataloging
"Descriptive cataloging" is a well-established concept in the tradition of library cataloging in which a distinction is made between descriptive cataloging and subject cataloging, each applying a set of standards, different qualifications and often also different kinds of professionals. In the tradition of documentation and information science (e.g., by commercial bibliographical databases) the concept document representation (also as verb: document representing) have mostly been used to cover both "descriptive" and "subject" representation. Descriptive cataloging has been defined as: "The part of cataloging concerned with describing the physical details of a book, such as the form and choice of entries and the title page transcription."
Subject cataloging may take the form of classification or (subject) indexing. Classification involves the assignment of a given document to a class in a classification system (such as Dewey Decimal Classification or the Library of Congress Subject Headings). Indexing is the assignment of characterizing labels to the documents represented in a record.
Classification typically uses a controlled vocabulary, while indexing may use a controlled vocabulary, free terms, or both.
Main article: Library catalog, History
Libraries have made use of catalogs in some form since ancient times. There is evidence of catalogs dating back to approximately 2300 B.C.E. in Sumer.  The Library of Alexandria is reported to have had at least a partial catalog consisting of a listing by Callimachus of the Greek literature held there.  The Chinese Imperial Library of the Han Dynasty of the 3rd century A.D. had a catalog listing nearly 30,000 items, each item similar in extent of its content to a Western scroll.  The first catalogs in the Islamic world, around the 11th century, were lists of books donated to libraries by persons in the community. These lists were ordered by donor, not by bibliographic information, but they provided a record of the library's inventory.
Many early and Medieval libraries in Europe were associated with religious institutions and orders, including the Papal library in Rome. The first Vatican Library catalog is from the late 13th century. These catalogs generally used a topical arrangement that reflected the topical arrangement of the books themselves.  Meanwhile, the Sorbonne library in Paris had accumulated more than one thousand books, and in 1290 their catalog pioneered the use of the alphabet as an organizing tool.
It was the growth in libraries after the invention of moveable-type printing and the widespread availability of paper that created the necessity for a catalog that organized the library's materials so that they could be found through the catalog rather than "by walking around." By the 17th century libraries became seen as collections of universal knowledge. Two 17th century authors, Gabriel Naudé, in France, and John Dury, in Scotland, both developed theories of systematic organization of libraries. The development of principles and rules that would guide the librarian in the creation of catalogs followed. The history of cataloging begins at this point.
Cataloging rules have been defined to allow for consistent cataloging of various library materials across several persons of a cataloging team and across time.
Anglo-American Cataloging Standards
The English-speaking libraries have shared cataloging standards since the early 1800's. The first such standard is attributed to Anthony Panizzi, the Keeper of the Printed Books of the British Museum Library. His 92 rules, published in 1841, formed the basis for cataloging standards for over 150 years. 
Subsequent work in the 19th century was done by Charles C. Jewett, head of the Smithsonian library, which at the time was positioned to become the national library of the United states. Jewett used stereotype plates to produce the library's catalog in book form, and proposed the sharing of cataloging among libraries. His rules were published in 1853. 
Jewett was followed by Charles Ammi Cutter, an American librarian whose "Rules for a Dictionary Catalog" were published in 1876. Cutter championed the concept of "ease of use" for library patrons. 
In the 20th century, library cataloging was forced to address new formats for materials, including sound recordings, movies, and photographs. Seymour Lubetzky, once an employee of the Library of Congress and later a professor at UCLA, was tasked to do extensive studies of the current cataloging rules over the time period from 1946-1969. His analyses shaped the subsequent cataloging rules. 
The published American and Anglo-American cataloging rules in the 20th century were:
- Anglo-American Rules, 1908
- American Library Association rules, 1949
- Library of Congress rules, 1949
- Anglo-American Cataloging Rules (AACR), 1967
- Anglo-American Cataloging Rules, Second Edition (AACR2),1978
- Revised Anglo-American Cataloging Rules (AACR2-R), 1988, 1990, 2002 <rev name="chan" />
The 21st century brought renewed thinking about library cataloging, in great part based on the increase in the number of digital formats, but also because of a new consciousness of the nature of the "Work" in the bibliographic context, often attributed to the principles developed by Lubetzky.  This was also supported by the work of the International Federation of Library Associations' work on the Functional Requirements for Bibliographic Records (FRBR), which emphasized the role of the work in the bibliographic context. FRBR created a tiered view of the bibliographic entity from Work to Item. This view was incorporated into the cataloging rules subsequent to AACR2-R, known as Resource Description and Access (RDA).
Germany and Prussia
The Prussian government set standard rules for all of its libraries in 1899, based on the rules of the University Library at Breslau by Karl Dziatz. These were adopted throughout Germany, Prussia and Austria. After the adoption of the Paris Principles in 1961, Germany developed the Regeln für die alphabetische Katalogisierung: RAK in 1977.
Cataloging codes prescribe which information about a bibliographic item is included in the entry and how this information is presented for the user; It may also aid to sort the entries in printing (parts of) the catalog.
Currently, most cataloging codes are similar to, or even based on, the International Standard Bibliographic Description (ISBD), a set of rules produced by the International Federation of Library Associations and Institutions (IFLA) to describe a wide range of library materials. These rules organize the bibliographic description of an item in the following eight areas: title and statement of responsibility (author or editor), edition, material specific details (for example, the scale of a map), publication and distribution, physical description (for example, number of pages), series, notes, and standard number (ISBN). The most commonly used cataloging code in the English-speaking world are the Anglo-American Cataloguing Rules, 2nd edition (AACR2). AACR2 provides rules for descriptive cataloging only and does not touch upon subject cataloging. AACR2 has been translated into many languages, for use around the world. The German-speaking world uses the Regeln für die alphabetische Katalogisierung (RAK), also based on ISBD.
In subject databases such as Chemical Abstracts, MEDLINE and PsycINFO, the Common Communication Format (CCF) is meant to serve as a baseline standard. Different standards prevail in archives and museums, such as CIDOC-CRM. Resource Description and Access (RDA) is a recent attempt to make a standard that crosses the domains of cultural heritage institutions.
Most libraries currently use the MARC standards -- first developed during the 1960s -- to encode and transport bibliographic data. These standards have seen critiques in recent years for being old, unique to the library community, and difficult to work with computationally. The Library of Congress is currently developing BIBFRAME, a new RDF schema for expressing bibliographic data. BIBFRAME is still in draft form, but several libraries are already testing cataloging under the new format.
Library digital collections often use simpler digital formats to store their metadata. XML-based schemata, particularly Dublin Core and MODS, are typical for bibliographic data about these collections.
Library items that are written in a foreign script are, in some cases, transliterated to the script of the catalog. In the United States and some other countries, catalogers typically use the ALA-LC Romanization tables for this work. If this is not done there would need to be separate catalogs for each script.
Ferris maintains that catalogers, in using their judgment and specialized viewpoint, uphold the integrity of the catalog and also provide "added value" to the process of bibliographic control, resulting in added findability for a library's user community. This added value also has the power to harm, resulting in the denial of access to information. Mistakes and biases in cataloging records can "stigmatize groups of people with inaccurate or demeaning labels, and create the impression that certain points of view are more normal than others".
Social responsibility in cataloging is the "fair and equitable access to relevant, appropriate, accurate, and uncensored information in a timely manner and free of bias". In order to act ethically and in a socially responsible manner, catalogers should be aware of how their judgments benefit or harm findability. They should be careful to not misuse or misrepresent information through inaccurate or minimal-level cataloging and to not purposely or inadvertently censor information.
Bair states that it is the professional obligation of catalogers to supply thorough, accurate, high-quality surrogate records for databases and that catalogers also have an ethical obligation to "contribute to the fair and equitable access to information". Bair recommends that catalogers "actively participate in the development, reform, and fair application of cataloging rules, standards, and classifications, as well as information-storage and retrieval systems". As stated by Knowlton, access points "should be what a particular type of library patron would be most likely to search under -- regardless of the notion of universal bibliographic control".
A formal code of ethics for catalogers does not exist, and thus catalogers often follow library or departmental policy to resolve conflicts in cataloging. While the American Library Association created a Code of Ethics, Ferris notes that it has been criticized for being too general to encompass the special skills that set catalogers apart from other library and information professionals. As stated by Tavani, a code of ethics for catalogers can "inspire, guide, educate, and discipline" (as cited in Bair, 2005, p. 22). Bair suggests that an effective code of ethics for catalogers should be aspirational and also "discuss specific conduct and actions in order to serve as a guide in actual situations". Bair has also laid out the beginnings for a formal code of cataloging ethics in "Toward a Code of Ethics for Cataloging".
Sanford Berman, former Head Cataloger of the Hennepin County Library in Minnetonka, Minnesota, has been a leading critic of biased headings in the Library of Congress Subject Headings. Berman's 1971 publication Prejudices and Antipathies: A Tract on the LC Subject Heads Concerning People (P&A) has sparked the movement to correct biased subject headings. In P&A, Berman listed 225 headings with proposed alterations, additions, or deletions and cross-references to "more accurately reflect the language used in addressing these topics, to rectify errors of bias, and to better guide librarians and readers to material of interest". Berman is well known for his "care packages," mailings containing clippings and other materials in support of changes to subject headings and against racism, sexism, homophobia, and governmental secrecy, among other areas for concern.
In "Three Decades Since Prejudices and Antipathies: A Study of Changes in the Library of Congress Subject Headings," Knowlton examines ways in which the Library of Congress Subject Headings (LCSH) has changed by compiling a table of changes described in P&A, followed by the current status of headings in question. Knowlton states that his intent for this table is to "show how many of Berman’s proposed changes have been implemented" and "which areas of bias are still prevalent in LCSH." In the discussion of Knowlton's findings, it is revealed that of the 225 headings suggested for change by Berman, only 88 (39%) have been changed exactly or very closely to his suggestions (p. 127). Another 54 (24%) of headings have been changed but only partially resolve Berman's objections, and "which may leave other objectionable wording intact or introduce a different shade of bias." 80 (36%) headings were not changed at all according to Berman's suggestions.
- Main entry or access point– generally refers to the first author named on the item. Additional authors are added as "added entries." In cases where no clear author is named, the title of the work is considered the main entry.
